123\SmartBMS is an easy to use yet advanced, modular BMS to keep your lithium batteries in perfect condition, increasing the lifespan of the battery pack. The system measures important data like cell voltages, cell temperatures and in- and outgoing currents. It also balances all cells to the same voltage during charging. The BMS supervises the whole battery pack and has two signal relays to indicate “allow to charge” and “allow to discharge”. These signal relays can control chargers and inverters with “enable”/”disable” signals or by connecting an energy efficient power relay to the signal relay. An example is the 123\SmartRelay. Easily connect your phone to the BMS using Bluetooth to see relevant information including state of charge, energy consumed, energy stored, in- and outgoing current, cell voltages and temperatures. With 123\SmartBMS, your battery pack is in safe hands.

Lifeline Lithium Batteries Bluetooth Monitor Features include, Percent State of Charge, Charge and Discharge status, Voltage, Amperage draw, Temperature, and Cell Balance. The Bluetooth app monitors each internal battery cell in real time. The Bluetooth monitor will help to extend the service life of the battery. 1. Real-time voltage, current, power, and other parameter values in the form of dashboard and digital display; 2. Real-time voltage and alarm status of all single cells. If the reported parameter triggers the alarm value or protection value, it will prompt an alarm; 3. Comparison of each data of the cell, the voltage difference. Maximum voltage cell Minimum voltage cell. and cell balance display 4. Cell temperature warning. Over-temperature, short-circuit, over-voltage, under-voltage real-time alarm. 5. Log the warnings that occur at each moment. 6. Compatible with all models of Lifeline Lithium batteries.
